More Than Blue
When people hear "Sapphire," they immediately imagine a deep, royal blue. While blue remains the standard, the Corundum family (which includes sapphire and ruby) is one of the most versatile in the gem world.
Any sapphire that isn't blue—and isn't red enough to be a ruby—is classified as a Fancy Sapphire.
The Rainbow of Corundum
The chemical formula for sapphire is simple: Aluminum Oxide (Al2O3). In its pure state, it is colorless (Leucosapphire). The "fancy" colors are created by trace impurities:
- Titanium + Iron: Blue Sapphire
- Chromium: Pink Sapphire (or Ruby if deeply saturated)
- Iron: Yellow and Gold Sapphire
- Iron + Magnesium: Green Sapphire
- Chromium + Iron + Magnesium: The legendary Padparadscha (Pink-Orange)
Part-Color and Teal Sapphires
Modern jewelry trends have shifted toward "Teal" and "Party" sapphires. Teal Sapphires (common in Montana, USA and Australia) blend blue and green. Part-Colored Sapphires show distinct zones of different colors in a single stone—typically blue and yellow.
When cut properly by a master lapidary, these zones blend together to create mesmerizing flashes of green or bicolor patterns that make every stone unique.
Conclusion
If you are looking for a sapphire but blue isn't your color, the world of fancy corundum offers a spectrum that matches any personality or design. Durable (Mohs 9) and incredibly brilliant, they are the perfect alternative for unique engagement rings or high-end collection specimens.
